According to a park spokesperson, a woman started down the Sky Splash water slide around 1:15 p.m.
However, she stopped somewhere on the slide, worried because of health concerns related to her back.
Because of her location on the slide, and out of "an abundance of caution," the park spokesperson said firefighters were called.
Those rescuers used a ladder truck to get to the woman, and put her on a backboard to prevent injury.
